To all whom t may Concern.'

VBe it known that I, FRANK M. PIERCE, av

citizen of the United Statesfand a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certainlnew and useful Improvements in to the accompanying drawings, and to thenumerals of reference marked thereon, which form a part of this specification.

This inventionrelates to a shuttle and constitutes a division of my co-pendlng ap- 15V plication for patent for tire wrapping machines filed October 3rd, 1914, Serlal No. 864,7 35. This type of shuttle when used in the machine is adapted to be opened to 'permit insertion of an annular obj ect thereinto which is to be wrapped, and then closed kand rotated at a high rate -ofspeed while the article is also moved' therethrough, soy

that a paper wrapping, the paper being carried upon a reel mounted upon the shuttle, is applied upon the article helically therearound. In this invention the shuttle is of an improved form, permitting ready opening and closing of the hinged sections thereof to permit insertion and removal of an article to and from the same.

It is an object, therefore, of this invention to construct a shuttle for a wrapping machine embracing sections hingedly Connected to one another and provided with locking means for locking theM same in closed position, together with paper carrying means to carry a reel of paper-for application to an article to be wrapped.

It is also an object of this invention to construct a shuttle consisting of hingedlyconnected sections, one provided With a spring impelled'looking bolt with mechanism thereon adapted to engage means on the other of said sections when the shuttle is swung into closed position to automatically release said locking bolt from "a re- .tracted position, permitting the same to be impelled into looking engagement, thus locking the shuttle sections one to another.

It is furthermore an important object of this invention to construct a shuttle Sprovided with hinged sections which, when in closed position, ali'ord a closed ring having an outer peripheral contact flange or sur- Specication of Letters Patent.

face andequippled'with automatically act- Ing locking mec anism which locks'saidsections one to.. another-,.when the same. are swung into closed position.

It -is finally an object of this` invention to provide a shuttle simple in construction and easily operated into an open or closed pos1t1on. I

The `invention (in a preferred form.) isV illustrated in the. drawings, and hereinafter more fully described. In thedrawings: l. Figure 1 is a view in elevation of a shuttle equipped with locking means embodying the principles of my invention.

Fig. 2 is a detail section taken on line 2 2 of Fig. 1.

Fig. 3 is a detail section taken o'n line 3-3 of Fig. 2, showing Vthe shuttle sections moving into a closed position.

Fig. .flis a central sectlon taken longitudinally through the shuttle locking mechanism with parts shown in elevation. ,Fig 5 is a fragmentary detail view illustrating a side elevation ofthe spring impelled locking bolt. i

Fig. 6 is a detail view of the complemental member therefor on the other shutl tle section.

As shown in the drawings: Theshuttle is an annulus inform, consisting of two sections denoted respectively as a whole by the reference numerals land 2, of which the section 1, for the most part is of angular cross section,.as clearly shown in Fig. 2, but which, at its ends, terminates in centrally disposed tongues of metal, that at one end of the shuttle section' being dented by the reference numeral 3, and that atthe other end by the reference numeral 1l. Said`shuttle section 2, is at itsmiddle portionof T'section, but at its ends terminates in yoke portions ,5 and 6, with the yoke por- 1.tion 5, engaged upon the tongue 3, of the Y section 1, and pivotally connected thereto by means of a stud screw 7. The other yoked end 6, of said shuttle section 2, is adapted to engage around the tongueend 4, of the shuttle section 1, and' saidl latter inthe tapered end S, of a locking bolt 9, projected through the registering apertures therein. Said bolt 9, is provided l'on itsend with a hand wheel l or actuating head 10,

andi is mounted within outstanding slotted Sleeve or cylindrical rnernloerv 11, provided with a web extension 12, which is se- 'lil cured to the .tace of the shuttle section 2,

by Ineens of a' holt 13, fr rigid collar 14,

is secured on seid holt '9, adjacent the tapered end 8, thereof, which has an outstanding pin 15, proj acting outwardly thererornthrough the slot provided therefor in the cylinder 11. A coiled spring 16, is wound about said holt .within said cylinder 11, and hears? at one of its ends against said collar 14e, and atfits other end against the "end Wall of said cylinder, thus normally inopelling the bolt into a locking position.

'An angled'plate '17, is vscoured upon the tongue end 4, of the shuttle section 1,hy means of ascrew .bolt 18, and is provided with a hey shaped slot 19, therein, `adropted to receive the pin 15', of the looking holt engaged Y 22, is a plate 24, projecting outwardly from which are a group of smooth ins 25, 2G, and-27, respectively, around which the strip of paper is trained, as clearly shown in Fig". 1, thus. ailording a tension device for the. paper. From the tension device the strip of paper is led through a curved folder plate 28, which is also secured upon the face of the shuttle section 1, and from there around a guide roller 29, from which it is led to the article being wrapped.

The operation is as follows: 4

4The shuttle as used in a wrapping inachine tracks upon its fiat rim or Contact 5l); around the tension pins and the reel 23, is

surface upon the driving element so that/ the shuttle is rotated at a high rate of speed and the paper being drawn around the idler roller 29, through the folder plate 2S, from applied to the article. The object is of course moved at the time the wrapper is.' applied thereto toinsure an application of the wrapper for the entire length of 'the article, whether it loe a long straight pipek or a curved object, such as a tire. "When the shuttle is at rest and it is desired to open the same to insert an article thereinto or remove a wrapped article therefrom, the operator` grips the hand wheel 10, and rotates the same a ,sulicient amount to swine; the pin 15, `which is rigidly connected with the lockin holt, out of engagement with the 'enlarged' inner end of the key shaped slot "i9, and then pulls outwarflly upon. the locking holt, giving the hand wheel a nal twist in the opposite direction of rotation to engage said pin 15, behind the shoulder 20. The shuttle section 2, may then loeswung outwardly about its pintle bolt 7, troni the shuttle section 1. l

ln locking up the shuttle after an article has been inserted therein it is only necessary to swing the shuttle section 2, into closed pos ition, whereupon the pin 15, on the locking holt strilres into the outer end oia the slot 19, of the plate 17, the edge of the slot being slightly chamtered ofi", as indicated hy the reference numeral 30, in Fig, 6. This causes the pin 15, to he thrust laterally from hehind the projection, 20, whereupon thev strong compression spring 16, within vthe containing cylinder 11, impels the. locking holt outwardly so that the tapered portion 8, thereof engages through the registering apertures of the yoke portion 6, of the shuttle section 2, and the ton-gue portion L1, of the shuttle section 1, thus locking the same together and of course then the pin 15, of the loclring bolt is enga-ged in the enlarged end oi' vthe slot 19.

ll ani aware various details of construction may he varied through a wide spring impellcd locking ineens in inactive position, and means automatically releasing said springA impelled locking means :for movement into a locking position when the shuttle sections are swung from an open 'to closed position.

2. ln a` locl'ng device of the class'described, hinged sections adapted to intert and having alined apertures, a slotted sleeve rigidly secured to one section, a locking holt vin the sleeve having one end adapted to engage in the alined apertures, a collar yon the holt inthe sleeve limiting the locking movement thereof, a spring on said bolt in said sleeve bearing against the collar to normally hold the bolt-thrust inwardly, a pin on the holt extending through the slot in the sleeve, and a notch in the sleeve adapted to receive the pin therein to lock the bolt when retracted.

3., 1n a locking device of the class described, hinged sections adapted to intert rigidly secured to one section, a locking bolt in the sleeve having` one end adapted to engage in thealined apertures, a collar on the l and having alined apertures, slotted sleeve 'bolt in the sleeve limiting the locking moveintent thereof, a spring on said bolt in said sleeve bearing against the collar to normally hold the bolt thrust inwardly, a pin on the bolt extending through the slot in the sleeve, a notch in the sleeve adaptedto receive the pin therein to lock the bolt When retracted, and means secured tothe =other section adapted to vengage said pin and adjust it out of the notch to release the locking bolt when the sections are closed. i.

4. In" a device of the class described hingedly connected sections, a spring impelled locking bolt on one of said sections, said sections provided lWith interfitting apertured members to receive said locking bolt projected' therethrough to retain the same closed in locked position, a slotted plate on the other of said sections, means retaining said locking bolt in an inactive position, and a pin mounted-0,11 saidbolt adapted to engage said slottedl plate to be released thereby from its inactive position, permitting the'bolt to be projected through said apertured interiitting members when thesections aremved from open to closed position.

In testimony whereof I have hereunto subscribed my name inthe presence of two subscribing witnesses..
